In contrast, our suspension system adopts a verticalized design, ensuring the rider's center of gravity remains consistently perpendicular to the ground. This guarantees a constant riding posture, providing a more comfortable experience for the cyclist.【Certification】 ISO4210/EN15194 Full compatible with sr Suntour ncx Sp12/sp17, Aventon, lectric xp 3.0/ 2.0/1.0 Xp lite xpress xpedition trike

The shims are super-lightweight and essentially invisible once installed
